Pearce challenger: Signs indicate Cortes a sham

On "Sunday Sqaure Off" this weekend, we hear from two newsmaker guests at the center of Arizona's most compelling stories:

--Jerry Lewis, who faces Republican Senate President Russell Pearce in a recall election that has state and even national implications.

Lewis, a first-time GOP candidate, tells me whether be believes the third Republican in the race, Republican Olivia Cortes, is a sham candidate, and whether the Pearce family put her up to running in the recall.

Lewis, who is a charter school executive and held top leadership positions in the Mormon church in the Valley, explains his position on illegal immigration and whether it amounts to "amnesty."

--Robert Shelton, the former University of Arizona president who took over as Fiesta Bowl executive director two months ago.

Shelton explains the steps he's taken to clean up the scandal-plagued organization; whether he believes the IRS will penalize the Fiesta Bowl; and whether the Big 12 will remain the bowl's major partner.
